Add white-space: nowrap to links in the sidebar

We already have overflow: hidden on these links, but if there is a
possibility to wrap, they will wrap. This happens in particular for trait
implementations because the punctuation (`<>, `) introduces opportunities
for breaks. That produces inconsistent UI. Fix it by forcing them not to
wrap.
